Interface

1. When the current flows in from positive direction: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V
2. When the current flows in from negative direction: V0=Vcc*0.5-la*K, V0=(2.5-0.06)V=2.44V
3. If it is an AC signal: V0=Vcc*0.5+la*K, V0=(2.5+0.06)V=2.56V

1. Make sure the current flows in from the positive direction. Adjust to the desired current warning level.
2. LED will be on when current is below the setting and DOUT will be low.
3. When the detected current is higher than your setting, the LED will turn off and the DOUT pin will go high.

1 x Power Chassis

This small adapter allows you to convert an existing micro USB power supply (like the official Raspberry Pi universal power supply for Raspberry Pi 1, 2 and 3) into a USB-C power supply.

Note that when a micro USB power supply is used, the maximum power that can be delivered to the Raspberry Pi 4 will be 12.5W. This means that less power will be available to devices connected to the USB 2.0 and USB 3.0 ports on the Raspberry Pi 4 than when using the new Raspberry Pi 15.3W USB-C power supply.

Specifications

• Female USB-B to Male USB-C adapter
• Compatible with Raspberry Pi 4 Model B (all variants)
• Carry on using your USB micro-B devices
